This bracket has a casing |4 pivotally secured thereto as at |5 so as to allow the board form Hi to be rotated from a vertical position to a substantially horizontal position. The board form is also rotatably mounted in the casing M as at Mia, and is allowed to have rotative movement about its longitudinal axis.

As has been previously stated, these forms are in a substantially vertical position while they are being passed through the drying chamber, not shown, and when they emerge from this chamber they are caused to assume a horizontal position as shown in Figure 1, so that a gripping mechanism such as indicated by reference character l8, may engage the toe and heel of the stocking and allow the form Hi to be withdrawn therefrom. The forms |6 are adapted to have a suitable stocking l1 mounted on the free end thereof, each of the stockings having an elastic top lla secured thereto.

During the change of position from vertical to horizontal, the form I6 assumes a position as shown in Figure 2 in its downward travel. It is necessary that the forward edge of the board be in a slightly lower plane when in horizontal position than the trailing edge, so that this forward edge will not contact the framework of the apparatus for holding the top of the stocking in a stationary position.

In order to produce this slight axial rotation of the form l6, about its pivot point |6a, a suitable roller has been secured to the shield |0a of frame In, (Figures 1 and 2). As the board form l6 rotates downwardly about its pivot point I5, the trailing edge of the board is allowed to contact the top of the roller 20 which will impart a slight axial rotation to the board, and then when the front edge of the board moves beneath the engaging roller 2| (Figures 1, 3 and 4), there will be no danger of the form striking the framework in which the roller is mounted, which might result in damage to the framework.

When the form has moved to a horizontal position, the finger motion l8 grips the heel and toe of the stocking along with the form |6. Upon further movement of the form away from the finger motion, the heel and toe of the form are withdrawn from the stocking and leaving the foot of the stocking engaged by the finger motion. At the same time, the roller 2| is resting near the top and upon one thickness of the stocking from which the form is being withdrawn. Since the elastic top l1a of the stocking will naturally cling closely to the form, it is evident that when this portion passes over the heel of the form, as shown in the right-hand portion of Figure 1, there will be a tendency for the stocking to stretch. If some means are not provided for holding the top stationary, the release of the stocking from this heel will cause the stocking to jump in a reverse direction from the direction of travel of the form and toward the finger motion I8. By providing the felt covered roller 2|, which has the proper contact with the top of the stocking at the point of removal, the top is held in a substantially stationary position during this release thereby allowing each stocking to fall downwardly on top of shifting table in a straight formation so that they may be easily handled in subsequent operations.

The roller 2| is rotatably mounted in inverted U-shaped frame member 26, which member is pivotally suspended as at 21 and 28 to upwardly projecting links 29 and 30, said links in turn,

being pivotally supported as at 3| and 32 to a support 33. The support 33 is pivoted to L- shaped member 35 which has slots 36 therein in which a bolt 34 is adapted to be adjustably mounted.

In order to adjust the position of the pivoted member 33, and its associated roller 2|, relative to the L-shaped member 35, a suitable set screw 31 threadably penetrates the laterally projecting portion of member 35 and has its end normally engaging the lower side of the member 33.

The free end of the member 33 has a member 39 secured thereto by any suitable means such as welding and the lower end of this member normally acts as a stop for projection 26a which is integral with the roller frame 26. In other words, the movement of the roller 2| to the left in Figmes 1, 3 and 4, is limited by the lower portion of projection 39. The right-hand end of the framework 26 has a pin 40 extending therefrom, said pin having its end penetrating a suitable slot 4| in a downwardly extending bracket 42, which bracket is secured to the pivoted member 33. The pin 40 has a compression spring 44 disposed therearound which spring has one end thereof engaging the frame 26 and its other end engaging bracket 42. This spring normally presses the member 26a against the lower end of the projection 33, but allows the frame and the roller to move an appreciable amount to the right, if, for any reason, the board form |6 should contact the felt lining 26b of member 26 while the form is being moved thereunder.

The upper end of the member 39 has notches 39a cut in opposed sides thereof which are adapted to fit in slot 45 of a support 46. This support 46 is L-shaped and has its downwardly extending leg secured to upwardly extending bar 41 by any suitable means such as bolts 48. These bolts penetrate slots 49 in the bar 41 and allow the entire framework to be adjusted vertically relative to the moving forms. An additional vertical adjustment may be effected by means of suitable set screws 50 which penertate slots 5| in the vertical leg of L-shaped member 35 and are threadably secured in member 46.

After the entire assembly has been adjusted to the proper position, thereunder with the stocking thereon and be properly engaged by the roller 2|. If, for any reason, the form should not be properly adjusted and the forward edge is accidentally allowed to contact the felt lining 26b, the parts will give way and assume substantially the dotted line position as shown in Figure 3, thereby preventing any damage.

After the form has been withdrawn from the stocking the conventional finger motion |8 will release the heel and toe to allow the stocking to fall downwardly upon the shifting table 25. At this time the next succeeding form l6 will move to the proper position where the finger motion |8 will again engage the heel and toe of the same, and at the same time, the roller 2| will engage the top thereof.

Figures 5 and 6 show a slightly modified form of the invention in which a roller engages the stocking during its removal from the form. This roller is mounted for vertical movement so as to allow it to be alternately raised and lowered. This roller 55 is mounted on a suitable U- shaped rod 56, which rod has its upper ends slidably mounted in framework 51. The rod 56 has adjustably mounted on each of its vertical the form 5 will move portions, collars 58 which normally support the 7 66 therein, said slot screw Tia penetrates the collar 0 turn, is pivoted to a bracket 82.

lower end of compression springs 59-, the upper end of the compression springs resting against the lower side of framework 51. These springs normally press the roller downwardly to a position where collars on .the upper ends of rods 56 will be in the position shown in Figure 5.

If, for any reason, the board form I6 would offer an excessive upward pressure, the springs 59 will give way, thereby adding a resilient feature to the roller. The frame 5? has upwardly extending prongs 510, and 57?) which are slidably mounted in the horizontally disposed portion. of a bracket 6|. This bracket extends upwardly from the floor of the building and has projections 62 and 63 integral therewith in which is slidably mounted a vertically disposed shaft 54. the upper end of said shaft having the lower end of bracket 57 secured thereto. Pivotally secured to the lower end of the shaft B l is a lever 65 which a slot being penetrated by a bolt 61. The lever 65 is pivoted intermediate its ends as at 68 to a bracket 69 and this bracket, in turn, is supported by platform 1!].

Upon counter-clockwise rotation of the lever 65 in Figure 5, it is evident that the rod M and the framework 51 will be moved upwardly. This upward movement is necessary when. the board form I6 is being moved beneath the roller 55. so that the roller and. the framework will offer no possible obstruction to the moving form. rotation of the lever 65, which is necessary to accomplish' this result, is eifected by means of a suitable bell crank lever l! which has a horizontally projecting leg "Ha which rests upon the lefthand end of the lever 65. A vertically disposed leg lib of the bell crank lever H has a roller 15! mounted therein which contacts a cam E3 on a drive shaft M. A spring '15 normally tends to hold the roller 12 in contact with this cam, whereas, a spring i6 is employed to normally hold the rod 64 and its associated framework 57 in lowermost position to a point where a collar T! will engage the log 52. In order to properly limit the downward movement of members 5'! and M, a set I! and has its end engaging the rod 64. This collar may be moved along the shaft M to the desired positi n until the proper adjustment has been effected. however. it is to he understood that the collar is only used a safety means for limiting the downward travel of the parts.

At the time the finger motion 2! hold of the toe and heel of the board to strip the stocking therefrom the roller 55 is lowered to eng e the top of the stocking on the board. The roller remains in this position until the stocking is cleared of the board, then it raises to an elevated position to allow the next board to move thereunder. As will be noted by the cam 73 in Figure 5. the duration of time that the roller 55 remains in contact with the top of the stocking and the board. is slightly greater than the time it re mains in an elevated position. This will insure that the top of the stocking will be properly engaged at all times during the removal of the form therefrom.

Sometimes it is desired to place the engaging 'means in an inoperative position, as in case when stockings with a nonelastic top are being dried. In order to accomplish this result, a stirrup is provided having its lower slotted end slidably mounted around the right-hand portion of lever 65. The upper end of this stirrup is pivoted to the horizontal leg of a bell crank 81 which, in The vertical "3 leg of the bell crank ti has one end of rod 83 secured thereto and this rod has teeth 84 on the lower side thereof which engage the lower portion of slot 85 in post 86. When the rod 83 is pulled to the right in Figure 5, the lever 65 is rotated in a counter-clockwise manner to raise the members 5i and 64 so that roller 55 will be in. a
